[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a service for processing plant data, and more particularly, to a maker or a data management company which provides services such as analysis and diagnosis of plant data or creation of various reports. (Less than,
(Collectively referred to as a storage manager) in a timely manner.

[0002]

2. Description of the Related Art Plants such as power plants have a wide variety of facilities.
Many sensors are attached to each part of the plant, and data servers and business terminals are installed in the site. The sensor signal from each sensor is taken into a control computer that controls the operation of the plant, and is used immediately as control data. It is transmitted to the server periodically and stored as history data. Some data may be input manually from the business terminal, and such manually input data is also stored in the data server as part of the plant data, similarly to the data from the control computer. You.

[0003] The plant data accumulated in the data server as described above needs to be periodically tabulated and subjected to detailed analysis and diagnostic processing. Such a service is usually performed by a plant maker. is there. On the other hand, conventionally, access to the data server of each plant is only possible from within the site of each plant, and access from outside the site is basically impossible. From this, conventionally,
In order for a manufacturer to provide services such as analysis and diagnosis of plant data at each site, a person in charge of the manufacturer goes to each site and analyzes and diagnoses the equipment data directly on the business terminal in that site, or , Needed data was taken out, brought back, and detailed analysis and diagnosis was performed after returning.

[0004] Further, in a site, a form for necessary items is created on a daily basis in order to constantly grasp the operation state of the plant. In creating such a form, various types of plant data are searched, displayed, and output on a business terminal within the site, and based on the displayed and output plant data, an operator at the site determines necessary items. They are written by hand in sequence. In this case, the items of the form include not only an item for simply filling in the displayed plant data, but also an item for which a plurality of data are required to be associated or related information is added as needed, or a certain item. Calculation items that need to be calculated are included.

[0005]

However, handling of plant data according to the prior art as described above has the following problems. First, since the data flow is a unidirectional flow in which the manufacturer analyzes and diagnoses the plant data accumulated in the site, there is a heavy burden on both the site and the manufacturer, and timely service is provided. There was a problem that it was difficult.

That is, since plant data is stored in a data server provided in the site, even if data analysis and diagnosis are performed by the manufacturer, data backup and management of the data server are not performed by an operator in the site. Was a burden. In addition, since the manufacturer cannot directly access the data server in the remote site, in order to provide services such as analysis and diagnosis of plant data at each site, the person in charge at the manufacturer must I had to go there. Furthermore, when detailed analysis and diagnosis of plant data cannot be performed on the business terminal on the site, and such analysis and diagnosis processing is performed after bringing back the data, until the analysis and diagnosis results are provided to the site side Sometimes a long time passed.

To solve this problem, it has been considered to install a data server on the maker side and transmit the plant data collected in the site to the maker side data server via a communication network. However, if plant data is sent from multiple sites to the manufacturer at the same time,
Transmission is concentrated and the data server and the network are overloaded, which may cause an operation error or a communication error.

[0008] Further, since the operator manually creates a form in the site, if an operator makes an entry error, he / she corrects the error itself by handwriting and recalculates the related calculation items. Correction was required, and if the value that was missed was related to another form, the form needed to be recalculated and corrected. On the other hand, it is conceivable that the report creation and correction work is performed mechanically by a computer. -There were problems such as the need to find forms that required printing in human systems.

The present invention has been proposed to solve the problems of the prior art as described above.
The plant data collected in the site can be transmitted to the storage administrator such as the manufacturer, and the transmitted plant data can be saved and managed appropriately by the storage administrator at any time. Another object of the present invention is to provide an apparatus and a method using a communication network so that a storage manager other than the above can provide services such as analysis and diagnosis of plant data in a timely manner. Another object of the present invention is to reduce the burden on the user in terms of capital investment costs, management labor, and the like, as compared to managing a plant data by independently providing a data server to a user.

It is another object of the present invention to prevent the concentration of transmission during the transmission of plant data and reduce the possibility of abnormal operation or communication in such an apparatus or method using a communication network. One. Further, in such an apparatus or method using a communication network,
One of the objects of the present invention is to make it possible to efficiently create and correct a form created on a site in order to grasp the operation state of a plant and to leave the correction history data thereof. .

Further, the data collection device is not necessarily limited to a fixed type, but may be a portable type. For example, a plant operator may travel around the plant together with such a portable type data collection device. Then, it is also possible to transmit the data of each facility to the data server side. In this case, it is more convenient to perform wireless communication between the data collection device and the data server. On the other hand, the data collection device and the user's business terminal do not necessarily need to be separate devices,
It is also possible to use a composite type device integrating them. When such an integrated data collection and business terminal is used, it is easy to confirm and correct data in the data server on the same device at the same time as sending data to the data server. it can. It is also possible to check and correct data before transmission.

A change history search unit 58 for searching the change history information file 53 for a change history for a period designated by the user is provided.

In this embodiment, as shown in FIG. 14, in order to display or print a list of forms that have been changed due to data correction, the form creation means 59 and the display means 60 for the created forms are provided. Is provided. The user-related information file 24 includes an item information file 55 storing data items necessary for creating a form in a format required by the user and a form information file 5.
6 are provided. Further, the data search and storage means 2
5 is provided with a related form search means 57. The related form search means 57 is for finding a form related to the corrected data and displaying it on the related form list screen 62. Note that FIG. 14 partially shows only a screen related to files and means necessary for the characteristic operation of the present embodiment from the viewpoint of simplification of the drawing.

[4-2. Operation of Fourth Embodiment] The operation of the present embodiment having such a configuration will be described with reference to FIGS.
7 and the flowcharts of FIGS. 18 and 19. In the present embodiment having such a configuration, as shown in FIG.
The data server 9 is accessed via the above data transmission / reception means 18 and the communication network 3 (S1801).
(S1802).
Then, the plant data (value, quality) selected by the user on this screen is corrected (S1803). in this case,
The user enters the corrected data and the reason for the correction. When the correction data is input from the business terminal 6 in this way (S1804), the correction unit 51 provided on the data server changes the plant data of the corresponding item on the server (S1805). Also, the change history information file 5
3, a change history (change date and time, item, data before correction, data after correction, reason) is added (S1806).

When the data is corrected in this way, the calculation means 52 searches the item information file 55 for an item related to the corrected data (S1807), and when recalculation is necessary (S1808). YES), the data necessary for the calculation is retrieved from the plant data file 23 by the plant data search and storage means 25 and the calculation is performed (S).
1809), the result is written into the plant data file 23 (S1810). In this case, if the content of the correction is a mere correction of character data that does not require recalculation (NO in S1808), the process ends without performing the recalculation.

Next, a description will be given, with reference to FIG. 19, of a process for displaying a related form or a list thereof when there is data that has been corrected or recalculated. First, when displaying a list of related forms, the user accesses the data server 9 using the business terminal 6 (S1901), and displays a menu screen prepared by the server 9 (S1901).
1902), display of the related form list screen 62 is selected.
Then, the related form search means 57 sets the item information file 5
5 and accessing the form information file 56 (S190
3.1904), the information is analyzed to determine a form related to the corrected data, and displayed on the related form list screen 62 (S1905).

On the other hand, the user selects a required form from the related form list screen 62 and makes a display display request (S1906).
YES). The form creation means 59 includes a form information file 5
6 and necessary information from the plant data file 23 (S1907, 1908), and create a form (S1).
909). The form display means 60 displays the form on the form display screen 63 or prints the form 64 at the request of the user.
(S1910).

When displaying the change history, FIG.
As shown in (1), the business terminal 6 accesses the data server 9 (S2001), displays an input screen prepared by the server 9 (S2002), and inputs a change history period to be referred according to the screen display (S2003). .
If the input period is correct based on the data accumulation period or the like (YES in S2004), the change history search unit 58 searches the change history information file 53 for a change history for the specified period ( If the change history is found during the period (S2005) (YE of S2006)
S), the searched change history information is displayed on the change history screen 65 (S2007). On the other hand, if there is no change history within the designated period, that fact is displayed, and the process ends. In this case, it is possible to prompt the user to input a new period for which the history is to be displayed.

[4-3. Effect of Fourth Embodiment] As described above, according to the present embodiment, the form related to the corrected data can be visually confirmed by displaying the list, and the changed form can be quickly displayed. In addition, if you perform data correction work, calculation work of related calculation items,
Form creation is performed automatically, and the work time can be greatly reduced.

[4-4. Modification of Fourth Embodiment] It should be noted that by adding a correction canceling means for restoring the correction of the plant data, it becomes possible to undo the change in the plant data caused by the correction work. Also, by adding information such as name, terminal IP address, login name, etc. to the correction history, if a user has tampered with plant data illegally, this user's identification work and modification work of tampering can be minimized. You can hold it down. In addition, your name,
By specifying the conditions and the period of the correction history such as the data ID, and adding a correction history search unit that searches the correction history for the correction that meets the conditions, it is possible to display only necessary information from the correction history. enable. As a result, since a correction history of a specific device can be displayed as a list, it is possible to predict a component replacement time from the cumulative number of corrections.

[4-5. Another Modified Example of Fourth Embodiment] a) It is possible to collectively display the listed forms. The man-hours for displaying the form can be reduced. b) The listed forms can be printed in a batch. The man-hour for printing the form can be reduced.

[5. Fifth Embodiment] This embodiment is characterized in that abnormal data is displayed in a font size proportional to the degree of abnormality from the limit value.

That is, conventionally, as a method of notifying a user of abnormal data on a sheet in a form, there has been a method of changing a font color of the abnormal data. However, simply changing the font color as in the past only serves as a material for determining whether the data is abnormal or normal.
Since the extent to which the abnormal data deviates from the limit value is not quantitatively presented, the user cannot instantly judge it. The present embodiment is to solve such a problem of the related art.

[5-1. Configuration of Fifth Embodiment] In this embodiment, as shown in FIG. 21, in addition to a plant data file 23 for storing plant data, limit value data for storing separately set limit values for each plant data The file 71 is provided. Further, a plant data management means 72 for performing a predetermined process on the plant data in the plant data file 23 is provided. The plant data management unit 72 refers to the limit value data file 71 and determines whether the value of the plant data is normal or abnormal, and the abnormal data detection unit 73 determines that the value is abnormal. And an abnormality degree calculating means 74 for calculating the degree of abnormality from the difference between the abnormal data and the limit value. On the other hand, the form creation means 59 described in the fourth embodiment includes a font size setting means 75 for setting the font of the abnormal data according to the degree of abnormality, and a font size set by the font size setting means 75 for the abnormal data. Is provided. In FIG. 21, only files and means necessary for the characteristic operation of the present embodiment are partially shown from the viewpoint of simplification of the drawing.

[5-2. Operation of Fifth Embodiment] FIG.
5 is a flowchart showing a procedure for displaying abnormal data in the present embodiment. That is, in the form work, the plant data management unit 72 uses the plant data file 2
At the time of processing the plant data in 3, a separately set limit value for each plant data is called from the limit value data file 71 (steps 2201 to 2203). Is checked (step 2204).

If the plant data is abnormal (NO in step 2204), the abnormality degree calculating means 74
In step 2, the "deviation degree" is quantified (step 2205). Next, the font is enlarged or the like by the font size setting means 75 according to the "degree of deviation" (step 2206), and the abnormal value is output to the form display means 60 (step 2207). Similar processing is performed for all plant data. On the other hand, if the plant data is normal in step 2204 (YES in step 2204), the process returns to step 2201, and the same processing is sequentially performed on all the plant data.

FIG. 23 shows an example of a display screen in this embodiment. In this case, the abnormality degree calculating means 7
The calculation of the “deviation degree” in 4 can be represented by the following formula. That is, the degree of upward departure = (| measured value−upper limit | / | upper limit−lower limit |) × 100 + 100,
Degree of downward deviation = (| measured value−lower limit value // upper limit value−lower limit value) × 100 + 100 (note: | A | represents the absolute value of A).

For example, if the upper limit of certain plant data is 4
When the lower limit value is 0, the measured value is 50 when the measured value is 50, 150% when the measured value is 10, and 200% when the measured value is 60. Then, the font size is set according to the “deviation degree”. That is, the font size is set according to the ratio of the standard character font size when the standard is set to 100%. For example, 100% = 20pt font (standard font), 150% = 30pt font (slightly large font), and 200% = 40pt font (large font).

However, since there is a restriction on the size of the character font, it is necessary to limit all fonts to the same font (for example, system maximum font = 60 pt) when the font size becomes 300% or more. Also, by having an "arbitrary coefficient" for how much to increase, if the change is too small or too large, the font enlargement rate can be adjusted, and the user can be accurately notified of the degree of abnormality. Can be. For example, in the case of 200%, the font size is usually twice, but when the coefficient is 0.75, 2 ×
0.75 = 1.5 times, 2 × 1.5 if the coefficient is 1.5
= 3 times the character font size.

[5-3. Effect of Fifth Embodiment] As described above, according to the present embodiment, it is possible to quantitatively specify how much abnormal data deviates from the limit value, and the user can instantaneously measure the abnormality of the measured value. The degree can be grasped. For example, if the displayed font size is very large, the data is obviously abnormal, and it may affect the plant operation. The order can be immediately determined by the user.

[5-4. Modification of Fifth Embodiment] In the above-described fifth embodiment, when abnormal data deviates downward, characters can be made smaller depending on the degree of the deviation. Thus, in the case of a downward deviation, the font is displayed in a small size, so that it can be easily grasped that the value is lower than the management value. In such a form, it is also possible to set the comparison target to the “previous value”,
In this case, it is possible to grasp how the current value changes from the previous value (for example, increasing or decreasing). Further, as shown in FIG. 24, the degree (%
Value) can be displayed together with the abnormal value in the cell on the screen of the correction function as it is. Thus, even in a system where the character font cannot be changed, the user can easily know the degree of deviation of the management value of the abnormal data. As a method of visually indicating the degree of deviation other than the font size, a bar graph may be displayed next to the abnormal value. Similarly, as a method of visually indicating the degree of deviation other than the font size, the color of the font of the abnormal value is continuously changed from green to red and displayed. For example, an abnormal value is displayed in green when the degree of deviation of the abnormal value is close to 100%, yellowish green in 150%, yellow in 200%, and red in 300%. this,
The color can be set by the user. This color change can be applied not only to the font color but also to the font background color.

[6. Sixth Embodiment] This embodiment is characterized in that when abnormal data exists in a form, the background color of the heading of each of the column and row where the abnormal data exists is changed.

That is, conventionally, as a method of notifying a user of abnormal data on a sheet in a form, there has been a method of changing a font color of the abnormal data. However, when a form becomes a large data sheet, it is troublesome to search for abnormal data in a wide sheet while scrolling the window. The present embodiment is to solve such a problem of the related art.

[6-1. Configuration of Sixth Embodiment] In this embodiment, as shown in FIG. 25, a plant data file 23 for storing plant data, and a limit value data file 71 for storing separately set limit values for each plant data. And a plant data management unit 72 for performing predetermined processing on the plant data in the plant data file 23 and an abnormal data detecting unit 73 for determining whether the value of the plant data is normal or abnormal. This is the same configuration as that of the embodiment.

In this embodiment, in addition to this configuration, a table information file 76 for storing a file in which each plant data is associated with sheet, row, and column information in the form, and an abnormal An abnormal data corresponding heading search unit 77 for searching for a heading of data is provided. The abnormal data corresponding heading searching unit 77 is connected to a form display unit 60 for outputting the heading items of the abnormal data in different colors. In FIG. 25, only files and means necessary for the characteristic operation of the present embodiment are partially shown from the viewpoint of simplification of the drawing.

[6-2. Operation of Sixth Embodiment] FIG.
5 is a flowchart showing a procedure for displaying abnormal data in the present embodiment. That is, in the form work, the plant data management unit 72 uses the plant data file 2
In the processing of the plant data in step 3, the limit value for each plant data set separately is called from the limit value data file 71 (steps 2601 to 2603). Is checked (step 2604).

If the plant data is abnormal (NO in step 2604), the abnormal data corresponding heading searching means 77 searches the table information file 76 for the heading item corresponding to the abnormal data (step 2605). Then, the background color of the searched heading portion is changed (step 2606), and output to the input / output device 67 (step 2607). on the other hand,
If the plant data is normal in step 2604 (YES in step 2604), the process returns to step 2601 and the same process is sequentially performed on all plant data. FIG. 27 shows an example of a display screen according to the present embodiment, in which the background color of the row / column heading of the table in which the abnormal data exists is changed.

[6-3. Effect of Sixth Embodiment] As described above, according to the present embodiment, even when sheets cannot fit on the same screen, the user checks only the headings to determine the presence or absence of abnormal data. can do. In addition, by following the cell from the heading that warns of an abnormality by a change in color, the location of the abnormal data can be immediately grasped. When the user wants to know the heading from the found abnormal data, the user can check the heading of the row or the column where the abnormal data exists without being affected by a mistake in tracing the cell.

[6-4. Modified Example of Sixth Embodiment] In the sixth embodiment as described above, the change color of the background of the heading is determined according to the stage divided by the limit value.
It can be set in multiple stages by the user. Note that the row / column heading where an abnormal value exists is not limited to changing the background color, but it is also possible to change the font color or blink the font. Also,
Similarly, depending on the row / column heading where the abnormal value exists, it is possible to set so as to display a warning on the screen. As a result, it is possible to immediately confirm whether an abnormal value exists in a headline having a high importance.

[7. Seventh Embodiment] This embodiment is characterized in that the number of abnormal data present in a sheet is displayed. That is, conventionally, as a method of notifying a user of abnormal data on a sheet in a form, there has been a method of changing a font color of the abnormal data. However, when the form becomes a large data sheet and a plurality of abnormal data exist, the user cannot immediately confirm how many abnormal data exist in the sheet. The present embodiment is to solve such a problem of the related art.

[7-1. Configuration of Seventh Embodiment] In this embodiment, as shown in FIG. 28, a plant data file 23 for storing plant data and a limit value data file 71 for storing separately set limit values for each plant data are provided. And a plant data management unit 72 for performing a predetermined process on the plant data in the plant data file 23, and an abnormal data detecting unit 73 for determining whether the value of the plant data is normal or abnormal. , The configuration is similar to that of the sixth embodiment.

In this embodiment, the abnormal data counting means 78 for counting abnormal data is connected to the abnormal data detecting means 72 for judging whether the value of the plant data is normal or abnormal.
Is connected to a form display device 60 that displays the number of counted abnormal data. Note that FIG. 28 partially shows only files and means necessary for the characteristic operation of the present embodiment from the viewpoint of simplification of the drawing.

[7-2. Operation of Seventh Embodiment] FIG.
5 is a flowchart showing a procedure for displaying abnormal data in the present embodiment. That is, in the form work, the plant data management unit 72 uses the plant data file 2
At the time of processing the plant data in 3, a separately set limit value for each plant data is called from the limit value data file 71 (steps 2901 to 2903). Is checked (step 2904).

If the plant data is abnormal (NO in step 2904), the abnormal data counting means 78 increments the abnormal data by one (step 2905), returns to step 2901, and sequentially returns all plant data. Repeat the detection of abnormal data for. After the determination as to whether or not all the plant data is abnormal data is completed, the number of abnormal data finally present in the sheet is counted (step 290).
6) The numerical value is output to the form display device 60 and displayed (step 2907). On the other hand, if the plant data is normal in step 2904 (YES in step 2904), the process returns to step 2901, and the same processing is sequentially performed on all the plant data.

FIG. 30 shows an example of a display screen in this embodiment, in which the total number of abnormal data in a sheet is displayed.

[7-3. Effect of Seventh Embodiment] As described above, according to the present embodiment, the user can immediately determine whether or not abnormal data exists in a sheet. In particular,
When abnormal data exists, the user can grasp the number of abnormal data, so that omission of correction at the time of data correction is eliminated. Further, the time of the abnormal data processing can be predicted from the number of abnormal data, which helps the user in managing the schedule.

[7-4. Modification of Seventh Embodiment] In the above-described seventh embodiment, when a plurality of abnormal data exist in the same sheet, as shown in FIG. It is also possible to display the number of abnormal data present in each column and row next to the heading. With this display, when abnormal data is searched for every column or every row of a table, oversight of abnormal data is eliminated.

As shown in FIG. 32, when a plurality of forms exist in the same sheet, the number of abnormal data for each form can be displayed. Further, as shown in FIG. 33, when a plurality of forms exist in the same sheet, the user sets a table group according to his / her preference and displays the number of abnormal data present in the group for each group. You can also. Furthermore, it is also possible to calculate the average data correction time by multiplying the number of abnormal data by the average correction time for each abnormal data, and to display the average data correction time on the screen as the estimated data correction time. Further, it is also possible to display a warning such as "there is too much abnormal data" on the screen according to the number of abnormal data. The user can also set the number of abnormal data and the contents of the warning that serve as the criterion.

[8. Eighth Embodiment] The present embodiment is characterized in that abnormal data in a sheet is collectively displayed as a list, and the data can be corrected in that state.

That is, conventionally, as a method of notifying a user of abnormal data on a sheet in a form, there has been a method of changing a font color of the abnormal data. However, when the form becomes a large data sheet and a plurality of abnormal data exist, the user cannot immediately confirm how many abnormal data exist in the sheet. In addition, when a plurality of abnormal data are scattered in the sheet, the data correction work is performed while searching for the location of the abnormal data. The present embodiment is to solve such a problem of the related art.

[8-1. Configuration of Eighth Embodiment] In this embodiment, as shown in FIG. 34, a plant data file 23 for storing plant data and a limit value data file 71 for storing separately set limit values for each plant data are provided. A plant data management unit 72 for performing predetermined processing on the plant data in the plant data file 23; an abnormal data detection unit 73 for determining whether the value of the plant data is normal or abnormal; and a table information file 76. In this respect, the configuration is the same as that of the above embodiment.

In this embodiment, the abnormal data detecting means 72 for judging whether the value of the plant data is normal or abnormal,
A table information file 76 for storing a file in which each plant data is associated with sheet, row, and column information in a form, and an abnormal data file 79 for storing abnormal data are provided. An abnormal data table creating means 80 for creating a list based on the abnormal data file 79 and the table information file 76, and a form display means 60 for displaying the created table are provided. Note that FIG. 34 partially shows only files and means necessary for the characteristic operation of the present embodiment from the viewpoint of simplification of the drawing.

[8-2. Operation of Eighth Embodiment] FIG.
5 is a flowchart showing a procedure for displaying abnormal data in the present embodiment. That is, in the form work, the plant data management unit 72 uses the plant data file 2
At the time of processing the plant data in step 3, the limit value for each plant data set separately is called from the limit value data file 71 (steps 3501 to 3503), and the abnormal data detection means 73 determines whether the plant data is out of the range of the limit value. Is checked (step 3504).

If the plant data is abnormal (NO in step 3504), the abnormal data file 79
Is stored (step 3505), and the process returns to step 3501 to sequentially repeat the detection of abnormal data for all plant data. Then, the determination as to whether or not all the plant data is abnormal data is completed, and finally, all the abnormal data existing in the sheet are stored in the abnormal data file 79. A list of abnormal data is created based on the file stored in the abnormal data file 79 and the contents of the table information file 76 (step 350).
6) The list is output to the form display means 60 and displayed (step 3507). On the other hand, if the plant data is normal in step 3504 (YES in step 3504), the process returns to step 3501, and the same processing is sequentially performed on all the plant data.

FIG. 36 shows an example of a display screen in this embodiment. The list includes a sheet number, title, data unit, abnormal data, limit value, and correction value where abnormal data exists. An input list is displayed. Further, the data is configured to be able to be corrected in this list.

[8-3. Effect of Eighth Embodiment] According to the present embodiment as described above, a user can immediately determine whether or not abnormal data exists in a sheet. In particular, when correcting abnormal data, the user can save trouble of searching for abnormal data each time by using the abnormal data list display. Further, when correcting abnormal data, omission of correction can be prevented, and the unit of data and the limit value are also displayed in the list, so that correction errors can be prevented. Furthermore, it is not necessary to display all data on the screen when correcting abnormal data, and the display can be used efficiently by minimizing the range of displaying the abnormal data list.

[8-4. Modification of Eighth Embodiment] In the above-described eighth embodiment, the previous value before the occurrence of the abnormal data may be displayed in the list. Also, as shown in FIG. 37, at the time of displaying the list, the number of corrected data can be counted, and the number of abnormal data and the number of corrected data can be displayed at the top of the table. Further, as shown in FIG. 38, it is possible to return from the abnormal data in the list display to the cells of the original table. The fifth
When used in combination with this embodiment, it is also possible to sort the abnormal data in the order of larger or smaller deviation and display a list of the abnormal data.

[9. Ninth Embodiment] [9-1. Configuration of Ninth Embodiment] FIG. 39 is a block diagram showing a configuration of a plant data server of an information processing system according to the present embodiment. As shown in FIG. 39,
This system is obtained by changing the configuration of the plant data server 9 in the information processing system according to the first embodiment described above.

That is, the form information management means 91 is added to the processing means 22 and the user-related information file 24
The form information file 92 is included therein, and the form information file 92 further includes a form overlay information file 93 and a search condition information file 94. Here, the form overlay information file 92 includes “form number”
And "form name", "form overlay data", and its "registrant" and "registration date" are stored in association with each other. The search condition information file 94 includes "form number" and "cell number", The search condition "point I
D "," date "," time ", and the like.

The form information management means 91 of the processing means 22 manages the search condition of each cell of the form set by the user, and, in response to a search condition list display request from the user, stores the form information in the form information file 92 in the form information file 92. Using the form overlay information file 93 and the search condition information file 94, search condition information set in each cell of the form is searched, and data for list display is output. The other parts are configured in the same manner as in the first embodiment.

[9-2. Search condition list display procedure] FIG.
Is a flowchart showing a search condition list display procedure in the present embodiment, and FIG. 41 is an explanatory diagram showing the search condition list display procedure using a specific screen or data structure. That is, in the present embodiment, first, when the user sets the output items of the form (form overlay setting) on the business terminal, the plant data server 9
Is input to the set form overlay information by the form information management means 91 (S400).
1), manage the output items of the form (S4002).

When a search condition list display request is received from the user (S4003), the form information management means 91 of the processing means 22 responds to the search condition list display request and stores the form information in the form information file 92. Using the form overlay information file 93 and the search condition information file 94, search condition information set for each cell of the form is searched (S4).
004), and transmits data for displaying a search condition list (4)
005). As a result, a search condition list is displayed on the user's business terminal as shown in FIG.

[9-3. Operation and effect of ninth embodiment]
As described above, in the present embodiment, the search condition of the form set by the user is managed on the plant data server side, and in response to a request from the user, for each form,
A list of the search conditions can be displayed on the user's business terminal. That is, in various conventional form creation support systems, search conditions that could only be requested, displayed, and confirmed for each cell can be displayed on one screen by one operation. Can be greatly reduced. Furthermore, since the setting information for each cell can be confirmed on the same screen, it is easy to compare each cell and confirm similar conditions. Therefore, according to the present embodiment, it is possible to greatly reduce the work of checking the search conditions set in each cell of the form by the user,
In addition, the efficiency of condition comparison for each cell and confirmation of similar conditions can be greatly improved.

[9-4. Modified Example of Ninth Embodiment] As a modified example of the ninth embodiment described above, a calculation formula set on a form is configured to be managed by the form information management unit 91. A list of calculation formulas set on a form can also be displayed. Further, it is also possible to collectively change a plurality of search conditions displayed in a list, such as a date, a point ID, and a search time. As one such modified example, FIG.
FIG. 43 is a flowchart showing a batch date change procedure.
FIG. 7 is an explanatory diagram showing the date batch change procedure using a specific screen and data structure.

In FIG. 42, the flow from inputting the form overlay information set by the user (S4201) to managing the output items of the form (S4202) is as follows.
This is exactly the same as FIG. Then, when the form date specification is received from the user (S4203), the form information management means 91 stores the form overlay information file 93 and the search condition information file 94 in the form information file 92 according to the form date specification. The search condition information set in each cell of the form is searched to change the date collectively (S420).
4) Transmit the changed data (4005). As a result, a screen in which the dates are changed collectively is displayed on the user's business terminal, as shown in FIG.

In this modification, the date information among the search conditions set by the user can be changed collectively on the user's business terminal, so that it is not necessary to change the date information for each cell. Can be changed in one operation. For example, if you want to change the date and output a diary of another date on a form such as a diary that displays a list of data for one day on a certain day, you can use a single operation to create a batch date in that diary. Since the date can be changed, the work of changing the date can be greatly reduced. Further, compared to a case where the dates are individually changed, omissions and mistakes of the dates can be eliminated. In addition, when changing the date, the daily report etc. may be changed on a daily basis, but since the seasonal report, monthly report, quarterly report, annual report etc. are summarized in each counting period unit, for example, if it is a monthly report, set it to the cell It is conceivable to change the date collectively for each report tabulation unit, such as changing the month in which data is collected.

In the form overlay information file 92, the “form type” such as daily report, seasonal report, period report, and annual report is defined as “form number” and “form name”, “form overlay data” and its “registrant” and “registration”. The data is stored in association with the date, and a form corresponding to an arbitrary form type designated by the user is searched from the form overlay information file 92 by the data search and storage means 25, and the results are displayed in a list on the business terminal of the user. I do. The user can arbitrarily select a plurality of forms from the list displayed and change the search times collectively. In this modified example, of the search conditions set by the user, the date information can be changed collectively for a plurality of forms on the user's business terminal, so there is no need to change the date information for each form.
